[SOLUTION] Insert Into has a varchar(max) issue

Insert Into has a varchar(max) issue

This type of 'Insert Into' has been working fine for me.
But, I have run into a situation where @sql is larger than 8000 characters.
I thought that if I declare @sql as varchar(nomax) I should get over 2 gb of space.
It seems to use 8000 not the larger 2 gb for MAX.

DECLARE @sql VARCHAR(max)

SET @sql = N'INSERT INTO [#IssuesDetails]
SELECT * from openquery
([GETPAID], '''
+ Replace(@sql, '''', '''''') + ''')'

EXEC (@sql)

I attached the error.
I can do a work around but wondering why this does not work.
It seems to ignore the NOMAX.
When I run the SSRS report with less parameter choices everything works fine.
This 'Insert Into' is reading records from Oracle tables and inserting them into a SQL table called #IssuesDetails

Here is complete statement:

Big misunderstanding.

The max size of the varchar(max) type is 2GB, the max length of a query is not coming from the type limit, but from the query length limitation.

I never heard of varchar(nomax) and doubt it exists.

The T-SQL side limitation is quite theoretical, 65536*network packet size. This already is lower than 2GB, as defatul packet size is 4KB, meaning it's 256MB. The driver you use might limit this further and other capacity limits are about complexity. You may find your limit here: https://msdn.microsoft.com/en-us/library/ms143432%28v=sql.100%29.aspx

Bye, Olaf.

Sorry, I meant MAX not NOMAX.

--build tbl_rmcore_gprecl table from Oracle table

You're finally excuting a openquery(), meaning a query to a linked server, most likely ORACLE, you're dealing with ORACLE limitations about that query.

Bye, Olaf.
